Arch Vessel Disease Flashcards
What is the MC cause of extracranial vertebral artery aneurysms
trauma
What is the gold standard for dx of vertebral aneurysm
Contrast angiography
Other than contrast angiography what other imaging is useful for dx
CTA or MRA
What is the MC branch of the aortic arch affected by aneurysmal ds
left subclavian artery
On physical exam what would one expect to find with a left subclavian artery aneurysm
supraclavicular bruit or blood pressure differences of over 20mm Hg between arms
What is the MC anomaly of the arch vessels
left common carotid from the brachiocephalic artery
Proximal subclavian occlusion can produce what syndrome
subclavian steal
Who should be treated for arch vessel occlusion
symptomatic patients
When is surgical intervention performed on the brachiocephalic artery
stenosis, aneurysm, dissection, trauma
Is surgery on the brachiocephalic artery open or endovascular
open
What approach is used to access the brachiocephalic artery
median sternotomy
Is bypass or endarterectomy more common in patients with aortic arch vessel disease
bypass
How is a proximal common carotid lesion treated
carotid subclavian transposition
What incision can be made to access the proximal common carotid artery
supraclavicular incision
Are TEVARs used for subclavian artery lesions
yes
